To illustrate the possible role of cerebral oximetry and stroke distance as measured by Doppler ultrasound in monitoring the critically ill patient non-invasively in the emergency department.
Five critically ill patients were monitored with either cerebral oximetry or both cerebral oximetry and stroke distance (the distance travelled by blood in the aorta with each ventricular contraction), as measured by Doppler ultrasound of the aortic arch.
Stroke distance as measured by Doppler ultrasound was a good clinical indication of reduced stroke volume and hence of cardiac output. Cerebral oximetry appears to be a useful measure of tissue hypoxia in patients in whom pulse oximetry is either unrecordable or unreliable.
阐述脑血氧饱和度测定以及通过多普勒超声测量的卒中距离在急诊科对危重症患者进行无创监测中可能发挥的作用。
对5例危重症患者进行监测，监测方式为单独使用脑血氧饱和度测定，或同时采用脑血氧饱和度测定及卒中距离（每次心室收缩时血液在主动脉中流动的距离），后者通过主动脉弓多普勒超声进行测量。
通过多普勒超声测量的卒中距离是每搏输出量降低进而心输出量降低的良好临床指标。对于脉搏血氧饱和度无法记录或不可靠的患者，脑血氧饱和度测定似乎是一种有用的组织缺氧测量方法。
